Using Gap Visualization to Navigate Multivariate Metabarcode Data, Select Primer Pairs, and Enhance Reference Data Quality

Environmental DNA, Volume 6, Issue 6, November–December 2024.
We introduce the metabarcoding gap visualization and demonstrated how it can make comparisons of PCR primers rapidly comprehensible for researchers in the molecular ecology community. We use gap visualization to simultaneously interrogate multiple primer pairs and enhance reference data quality. This has significant impact for study design as selecting

Continuous tooth replacement: what can teleost fish teach us?

Biological Reviews, Volume 99, Issue 3, Page 797-819, June 2024.
ABSTRACT Most tooth‐bearing non‐mammalian vertebrates have the capacity to replace their teeth throughout life. This capacity was lost in mammals, which replace their teeth only once at most. Not surprisingly, continuous tooth replacement has attracted much attention. Classical morphological studies (e.g.
